Re: Inserting a blank date value in database - ASP.NET Discussion Boards

You are getting the row index from the gridview, but you're manipulating the rows in the session data table. As a result, as soon as you remove one item, the number of rows is no longer the same, nor will the indexes be the same.

Thanks Sir. I was making that silly mistake.
Thank you very much.

cheers,

Hi Sneha,

You can delete by getting the rowID. After gettin the rowID, you can run code which you have written.

hope this will help

Hi ,
i want to insert null for date,when i do this database is taking date as 1900-01-01 , i want it to be blank , i am doing, add and edit pages,when i retrive data while editing date is coming as 1900-01-01 , help me resolving this.

cancellation_date date,
i am using syabase as database,

Well, does your column accept nulls ? It doesn't sound like it, it sounds like somewhere, the code or the database is inserting a default value.

This has nothing to do with ASP.NET.

Thanks for the reply,
the column accept nulls , through code i am not inserting any default values , how to stop databse inserting default values.

Impossible for me to say, because, again, you're not showing me any code. You either have a default value for the column which is being inserted for some reason, or there's something wrong with the code that is doing the inserting. I'd start in the database manager for your DB, and do some inserts into that table from there, and see what happens, to see if the problem is your DB code or your .NET code.

OK, this is for school work ? No-one is paying for this code, right ?

A malicious user can trivially erase your entire database.

As to the code, You're storing dates as strings instead of a date type. Doesn't your db have a date type ? This means that something in your code has to be doing the conversion. Which variable in this mess is the one that's being changed ? you've stepped through the debugger and you're sure a null is being passed ? I don't see how that is possible, a string from a textbox is never null.

Hi All,

I have one problem.I have done chat application.but my problem is:

suppose one customer and four employees are online.customer wants to chat perticular employee.First i want to send message to that perticular employee:"pls be online,customer wants to chat".

but my problem is how can i send this alert message to perticular employee who selected by customer?

This is the web appication.

pls help as early as possible.

Thanx

You obviously cannot, unless it's via email. This is an obvious limitation of a web app, if they are not on your page, you can't send them anyting.

Assuming the employee with whom the customer wants to chat is online, then doesn't your apppllication allow them to chat to them already - isn't that what a chat application is for?

If the employee is not online then, obviously, you can't send a message to them (well, you could phone them up, or email them, or send them a telegram, but if they're not using the chat application you're stuffed)

Hi There,
I am working with Asp.Net 2.0 with C#.net. In my project I had created a error message box using Div tag.If I run the project in Mozila 2.0 then it runs properly but when I run the project in enternet explorer 6.0 then it didnt show the message box.
What is the problem.Can anybody help me.

Thanks

enternet explorer ? I'm sorry, that's hilarious.

The problem is that your code is broken. Duh. Perhaps if you gave us code, we could try to help you, but, broadly, it's always the case that you should test across all browsers you're targetting, and be ready to rewrite something if it doesn't display properly in some browsers.

Thanks For Reply,
This Code I had written in Master Page it is working properly in Mozila 2.0.

function showBox(str)
{
var width = document.documentElement.clientWidth + document.documentElement.scrollLeft;

var layer = document.createElement('div');
layer.style.zIndex = 2;
layer.id = 'layer';
layer.style.position = 'absolute';
layer.style.top = '0px';
layer.style.left = '0px';
layer.style.height = document.documentElement.scrollHeight + 'px';
layer.style.width = width + 'px';
layer.style.backgroundColor = 'LightGray';
layer.style.opacity = '.7';
layer.style.filter += ("progid:DXImageTransform.Microsoft.Alpha(opacity=80)");
document.body.appendChild(layer);

var div = document.createElement('div');
div.style.zIndex = 3;
div.id = 'box';
div.style.position = (navigator.userAgent.indexOf('MSIE 6') > -1) ? 'absolute' : 'fixed';
div.style.top = '200px';
div.style.left = (width / 2) - (400 / 2) + 'px';
div.style.height = '100px';
div.style.width = '400px';
div.style.backgroundColor = 'White';
div.style.border = '4px solid silver';
div.style.padding = '20px';
document.body.appendChild(div);

var myimg = document.createElement('IMG');
myimg.src= "../images3.jpg";
myimg.width= '50';
myimg.height = '50';
myimg.visible="true";
div.appendChild(myimg);

var p = document.createElement('p');
p.innerHTML = str;
p.style.position = "absolute";
p.style.top = '20px';
p.style.fontSize=14+'px';
p.style.fontWeight = "bold";
p.style.left = (width / 2) - (800 / 2) + 'px';
div.appendChild(p);

var btn=document.createElement('Button');
btn.innerHTML='Ok';
btn.style.border='2px solid silver';
btn.style.opacity = '.6';
btn.style.fontSize=16+'px';
btn.style.fontWeight = "bold";
btn.style.border='solid';
btn.style.position = "absolute";
btn.style.top = '100px';
btn.style.left = (width / 2) - (620 / 2) + 'px';

btn.onclick = function()
{
document.body.removeChild(document.getElementById('layer'));
document.body.removeChild(document.getElementById('box'));
};

div.appendChild(btn);
}

OK, well, that's probably because IE ignores standards, but you have no choice but to work out which bit IE is ignoring, and to do something about it. I'd just google for code to do this, and expect that someone else has solved this already.

I promise you, I am doing my own work, not yours. Browser compatibility is a nightmare, your bet bet is to google for a script that handles this.

Dear fellows

I've been fiddling about with some code I inherited that I hoped would allow me to delete users from my database.

The users are actually part of the asnet users scheme not just a simple record table.

I'm getting the error message stated in the title of my query.

The funny thing is, is that it seems to be deleting the user but also returning me the error essage.

can anyone tell me what is going wrong?

I've been googling but not had much luck.

Thanks in advance.

Here's what I'm doing..............

I'm trying out that FreeTextBox control but wondering how you can pass it an HTML file to display at runtime?

'that FreeTextBox control' - what on earth are you talking about ?

I doubt very much that there would be a textbox control that displays HTML as HTML, but, gosh, if I had such a control and was wondering, I'd look for it in the docs and pass it some HTML to see what happened.

Hello All,

I have got a web design template in .HTML format. I want to parse the html file and convert that into .Aspx format programatically and then add to my ASP.Net project and start coding that.

for e.g. if i have tag in my html page, i want this to be converted as an asp.net control programatically
<asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown">

I want for all the html controls to be converted into asp.net controls.

Is there any tool available for this.

Thanx in Advance

No, there is not.

Is there any other way to do it, if tool is not available?
Give me some sample example.

Thanks in advance
